摘要： A power transmission apparatus for a vehicle may include: a first, second, third, and fourth input shaft; an output shaft; an idle shaft; a fixed transmission performing shifts to fixed shift stages depending on gear ratios of four change gear trains; and a torque assist driving and electronic continuously variable automatic transmission performing a torque assist for a torque input from the fixed transmission and performing electric vehicle driving and electronic continuously variable automatic transmission functions to output the torque through the output shaft. The disclosed power transmission apparatus implements fixed shift stages of four forward speeds and one reverse speed in a dual clutch transmission (DCT) structure that uses three synchronizers. The disclosed power transmission apparatus improves fuel consumption and acceleration performance by adding one planetary gear set and a motor/generator to enable driving in an electric vehicle (EV) mode and an electronic continuously variable automatic transmission (e-CVT) mode.
